摘要
In a process for producing urea with ammonia and pure carbon dioxide as starting materials, the improvement comprises feeding liquid ammonia in part to the absorber (1) with all the carbon dioxide and in part to the synthesis reactor (2). The NH3/CO2 molar ratios are 2 to 4 for the condenser and 2.5 to 7 for the reactor. Film-type absorbers are preferred. IMAGE
